Some placer deposits of phenomenal richness occurred. A strip of 

 ground 75 feet wide and 1 mile long which was worked in the sixties 

 produced $2,000,000, a single pan of gravel sometimes yielding as 

 high as $300. The gold is coarse, 50 per cent of the product aver- 

 aging 25 cents or sometimes more to the color while nuggets 25 grams 

 in weight are not uncommon. The average value of the placer gold 

 is $18 an ounce. A sample of placer gold from Hurd's Claim, Loon 

 Creek, mined in 1869, (Cat. No. 55763, U.S.N.M.), consists of small 

 dark-yellow nuggets which are irregular and much flattened. 



In the Stanley Basin district some narrow quartz veins in granite 

 carry gold. The chief production, however, is from the placers of 

 Stanley Creek and Joes Gulch, which have yielded about $100,000, 

 the average return for some years varying from $3,000 to $4,500 a 

 year. The gold is coarse — flax to wheat size— and runs 0.717 fine 

 (71.70 per cent Au) bringing $15 an ounce. At the Willis dredge 

 property the gold, which is concentrated on the bedrock, is worth 

 only $13 an ounce. The gold here is associated with native amalgam 

 and cinnabar while elsewhere in the district the rare earth mineral 

 brannerite has been found in the placers. 



Gold occurs in the Yankee Fork district with silver in veins of late 

 Tertiary age in volcanic rocks, the gangue being fine-grained quartz 

 and adularia with some opal and chalcedony. The gold is usually 

 very finely divided and is concentrated in narrow dark streaks in the 

 vein, which react for selenium. Some coarser gold is reported from 

 the Morrison vein. The oxidized ore consists of firm quartz heavily 

 stained with iron and manganese oxides. The principal vein mines 

 are the General Custer, Lucky Boy, Charles Dickens, Momson, 

 Golden Sunbeam, McFadden, etc. Placers which have produced 

 gold to the value of $50,000 were discovered on Jordan Creek in the 

 middle seventies. One nugget weighing nearly a kilogram was found 

 near the outcrop of the Morrison vein, others weighed several hundred 

 grams, and many exceeded 25 grams. A specimen lot of gold (Cat. 

 No. 55,475, U.S.N.M.) mined from Bairs (or Blairs?) claim on 

 Yankee Fork consists of fine flattened scales 2 mm. in maximum 

 diameter. 



ELMORE COUNTY 



In the Atlanta district the gold production from the Atlanta lode 

 has been considerable, some portions of the veins being predominantly 

 gold-bearing, although the district is best known for its phenomenal 

 silver ores. 



In the Black Warrior district a nominal production of gold has been 

 obtained from lode mines, chiefly the Double Standard, White Ribbon, 

 Fourth of July, and Magnolia.
